Crash on Open Project 4.8

I’ve been having a huge amount of trouble opening a project that was given to me by a lecturer. It opens in 4.7.2 without issue, on my laptop and on a uni computer. However I have 4.7.6 at home. I tried migrating it, and created a 4.8 version, which then opened on my computer with a few bugs, but then closed itself and now won’t open again.

Here’s the report:

Try building the engine from source and convert your project to the new engine version. 4.8 is in preview status yet. So you should wait for its release.

or

Restore your project by using old saves or I hope you saved your project’s folder before :slight_smile: I forgot this many times…
